SPECIFICATION forming part of Letters Patent No. 655,81 '7, dated August 14, 1900.

Application tiled March 5V, 1900l Serial No. 7,393. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM JOSEPH WAY- LAN, a subject of the Queen of Great Britain and Ireland, residing at 284E High street, Sutton, in the county of Surrey, England, have i11- vented an Improved Plumbers Shave-Hook, also applicable as a gage and as a marker or cutter for making washers, of which the following is a specification. l

This invention relates to an improved plumbers shave-hook, whichlis also applicable as a gage and as a marker or cutter for making washers. y Heretofore in the use of plumbers shavehooks of the ordinary construction considerable inconvenience is often experienced in marking and shaving any inaccessible under part or other part of a lead pipe preparatory to making a wiper-joint even when using a looking-glass therewith, andthe same remark applies also to a certain extent to other constructions which have been suggested. Oertain of these other constructions also have been open to objection on the score that While being excellent in use in some situations they have been exceedingly awkward to use or even useless in others. Now according to this inventionl produce a plumbers shave-hook which, while applicable to all open and also awkward situations, aiiords absolute accuracy and expedites Work. It is provided with a gage, which is useful for limiting the stroke of the hook when shaving, say, the end of apipe, which gage is further of great utility as a circle cutter or marker, and, besidesthis, the gage is so constructed as to serve as a protector to the point of the shave-hook blade at will and yet is capable of being iixed out of the way when shaving a flat piece of lead.

Figure l of the accompanying drawings is a side elevation of my improved plumbers shave-hook, and Fig. 2 is an end elevation thereof. Fig. 3 is a view representing the tool when applied to mark or shave the end of a pipe, and Fig. is an end elevation thereof. Fig. 5 represents in elevation the tool when applied to mark or cut a line parallel to the edge of a sheet of metal, such as lead. Fig. 6 shows the mode of applying the shavehook when used as an inside gage--for example, in measuring the distance for scraping from the edge in the angle of a leaden cistern during the making of same; and Fig. 7 is a view indicating the Way the tool is used to mark or cut a circle.

The same letters of reference refer to like parts in all the figures.

I provide the shank or stein A, Figs. 1 and 2, With division -lines, say, in inches. and eighths of inches, as shown, and also, if desired, divisions according to other measurements suitable for the variousliinds of work most commonly occurring, and, further, l provide on the said shank a sliding gage or pointer B, formed with a more or less blunt point and made to iix, for example, by a thumb-screw C, in any desired position or to any of `the aforesaid division-lines at the desired distance from the head or blade D of the shave-hook, and the radial length of the gage B is about equal to or slightly greater than the length of the blade, so as to serve as aV protector or guard to the point of said blade when clamped against same. (See, for instance, Fig. 2.) It is, however, essential that the gage in other directions should be of as small dimensions as possible.

In shaving or scraping the outside of a piece of pipe-as shown in Figs. 3 and 4 for instance-the gage B is held up against the end of the pipe E and the shaving of the pipe is effected by drawing the tool toward and past the said pipe end. Stroke after stroke is taken until the whole of the end ofthe pipe has been scraped, and the scraping or shaving will. be uniform all around. If it be merely required to mark the pipe at a certain distance from the end, the gage B is held up against the pipe end and the tool is moved around the pipe concentrically therewith, the effect of which will be that the blade D accurately makes a mark all around. The tool may also be used for marking sheet or other more or less dat lead, as indicated by Fig. 5, the gage B in this case serving as the marker and the blade being in contact with the edge of the lead F. Fig. 6 represents another way of using the tool for either marking With the point of the gage B on the side G of, say, a cistern or the like to be soldered, or the blade D is pressed, say, against the side H when drawnback'- ward and forward to effect the scraping or shaving thereof.

IOO

n lusing the shave-hook as a pair of compasses or as a cutter for cuttin g circles in lead, leather, or the like the gage B is clamped on the shaft A, so that the points of the gage B and of the blade D are at the proper distance to agree with the radius of the circle'to to revolve under the tool, all as found most convenient. The dotted circle K represents the mark or cut which the tool will make.

What .I claim as my invention, and desire to secure by Letters Patent, is-

l. A plumbers shave-hook, comprising a handle', a shank, aknife or hook secured thereto and a pointed gage adjustable on said shank, the major diameter of said gage equal naine to this specification in the presence of two subscribing Witnesses.

to or slightly greater than the like diameter of the hook, for the purpose set forth.

2. A plumbers shave-hook comprising a handle, a shank, aknife or hook secured thereto and a pointed gage adjustable on said t shank, the major diameterof said gage equal to or slightly greater than the like diameter of said hook, the least minor diameter of which is greater than the least minor diameter of the gage, for the purpose set forth.

' 3. A plumbers shave-hook comprising a handle, a graduated shank, a knife or hook secured tothe end thereof, anda pointed gage adjustable along said graduated shank and having a plain outer faee and a major diameter equal to or slightly greater than the like diameter of the hook, substantially as and for the purpose set forth.

4E. A plumbers shave-hook comprising a handle, a shank, a V-shaped knife or hook having a convex heel end secured to said shank, and a pointed gage adjustable on the shank and havinga major diameter equal to or slightly greater than the like diameter ofY the hook Whose least diameter is greater than the like minor diameter of the gage, for the purpose set forth.

In testimony whereof I have signed my WILLIAM JOSEPH WAYLAN.
